I'm having what appears to be the opposite problem as a lot of you with the SMS/call blocker - it's blocking 90% of my incoming calls and messages. These aren't hidden or anonymized senders; most of the time, they're in my contacts list. Lumia 822 Amber with the GDR 3 dev preview (which I fully understand may be the source of the problem).
coinneachfitzpatrick, this is very ironic. Did you download a 3rd party application that blocks sms messaging and calls from contacts saved on your device?
